Product Description

 

High Voltage Gas Insulated Vacuum Switchgear 400A 1140V For Underground

 

 

Description:

 

KBZ-500/1140 Mine explosion-proof switch intelligent vacuum feed for the coal mine, in AC 50HZ,voltage of 1140V or 600V, current up to 500A of the ungrounded three-phase grid with a voltage, overload , short circuit, leakage blocking, leakage protection, selective leakage.

KBZ-630/1140(660)Z mine use flame-proof intelligent vacuum feed switches are suitable for underground mines containing explosive gas (methane) and coal dust. They are is used as general switches for power distribution, or branch switches in a 50Hz, 1140V or 660V and current up to 400A (630A) 3-phase electrical network with non-directly earthed neutral. They have protection functions for short circuit, overload, phase failure, leakage, leakage-lockup, under voltage and overvoltage. FLEX I/O control module may be provided as an option for realizing remote monitoring. They employ a 16 bit MPU for intelligent control, using Chinese(English) character LCD to display fault signals of the running parameters. They detect current and output of fault protections. They adopt rapid door-open structures. They provide a built-in control module, FLEX I/O, as an option for remote control.


 

Competitive Advantage:

 

16-bit MPU intelligent control, Chinese (English) character LCD to indicate fault signals of the running parameters, detection of current and output of fault protection, rapid door-open structure and the built-in optional module FLEX I/O for remote control.
